============================================
Explanation:
Assuming each kick is independent of any other, this means the probability of making two field goals in a row is 0.8*0.8 = 0.64
The probability of missing any single field goal is 1-0.8 = 0.2; so the probability of missing two in a row is 0.2*0.2 = 0.04
----------------
Extra info:
Adding up those results shows that 0.64+0.04 = 0.68 is the probability of either making 2 in a row or missing 2 in a row; that leaves 1-0.68 = 0.32 to represent the probability of making exactly one field goal in either order.
Or you could note that 0.8*0.2+0.2*0.8 = 0.32
You need to see what you need to convert and how you need to convert it, do you need to divide to find out how many it goes in? Questions like that.
Set this up like a right triangle with the height of the triangle as 30, the angle across from that side, the reference angle, as 55, and the base is your unknown, x. This means that we have the angle, the side across from it, and the side adjacent to it. That sounds like the tangent ratio to me! Tangent of the angle is the side opposite over the side adjacent:
. Solving for x:
. Do that on your calculator in degree mode to get that the distance between the base of the ladder and the wall is 21 feet
